Sony Xperia Z runs on Quad-core 1.5 GHz Qualcomm processors and boasts of 2GB RAM. The screen is 5-inch TFT Reality display with Bravia Engine 2 for shaper picture and better clarity. The phone comes with a 13.1 MP rear-end snapper and 2 MP fully HD front camera. Slightly thicker than the ultra-slim smartphones, Xperia Z is 7.9 mm thick. Specifications apart, the phone is packed with a host of other features. The highlight of the phone is it is a “bath-friendly” phone. Sony Xpaeria Z is water resistant and can survive for 30 minutes in one meter of water. Definitely good news for those who bundle their phones in plastic at the mere sight of water! And that is not all. Sony Xperia Z comes with a special Battery Stamina mode. The mode reportedly improves standby time by four times. The apps are automatically shut when the screen is locked and are re-activated when the screen is brought back on.
